<h2>
<a NAME="LOCAL_HSFC"></a>Local Ordering with Hilbert Space Filling Curves (HSFC)</h2>
This is a local geometric ordering method that uses Hilbert space filling curves
to order the vertices located at specified coordinates.  This method assumes the
data to be ordered is local to the process and the query functions should
reflect this.

<p>
For more information on the HSFC algorithm, see the 
<a href="ug_alg_hsfc.html">HSFC algorithm documentation</a>.
